I was thinking of a new breed of Norn: the Platypus Norn.
It could be amphibious from birth (can stay under water for a long while but can still drown, like young Deep Norns) and it prefers eating fish (critters) over fruit (but it can still eat land food). It would, obviously, look like a platypus and it would be very tiny at birth, then grow up to be only the size of a youth Norn when it's fully grown.

I would make these myself, but I'm one of those people who doesn't know how and is too lazy to learn how. XD

I want a label agent, so I can make little signs to put up in my environments. They'd help with things like remembering which buttons do what on seed vendors, or what plans I had for which rooms the last time I was playing that I was only halfway finished with but can't remember now. :-/

Optimist: the glass is half full.
Pessimist: the glass is half empty.
Engineer: the glass is twice as big as it needs to be.

A plant with a cure in it, a weed with a poison in it, and a critter that feeds on both, with equal opportunity.

If the critter feeds on the plant, it stores the cure in its body, which it then gives to the norn when the norn eats it. If the critter feeds on the weed, it stores the poison in its body which it then gives to the norn when the norn eats it. If the critter feeds on both, the poison and the cure cancel each other out.

Gadgets that decay if they're left unattended in the ettin terrarium.

A connectable 'ear', to be attached to vendor agents - if it hears 'hungry for X', it will send a message to the vendor to vend.

There are 5 rooms for the Children of Capillata, right?
1. Universal Hub
2. Catillipac
3. Daedalus
4. Chione(In development I assume)
5. and another but I forgot its name. Morpheri, if I'm not mistaken
Four more and we could probably make a new game like Edynn tried to do. That is, if we could get the heatpan working and add an egg layer(Possibly as part of the Empathic Vendor(which could also get that toy update) with the list interface over the "blobby core" thing).
Room 6 could be the Workshop plus an Airlock, probably with Recycler, Spewers, Volcano button (for Daedalus) and Ettin & Grendel stuff.
Room 7 might be the Biodome, you know, because the ship needs a biodome.
Room 8, probably something along the lines of the infirmary
Room 9, I don't have the foggiest ideaThe Lake/Reservoir mentioned below
We can also link the meso door to the comms room.
If we want more rooms, replace the Universal Hub with the Hub.

EDIT: Does anyone have images for the C3/DS and CV Backgrounds? I have C1 & C2.

How about something similar to the quirky cookie machine that lets you make things besides cookies? Maybe can collect & toss in different types of fruit to make juice, wine or beer, collect & toss in seeds to make cakes, pasta & pies, toss in food & leaves to make medicines & different flavors of cheese. There are lots of possibilities.

Edit: The main reason I suggest it is because the quirky cookie machine is something you could only get from one of the norn add-on packs. If you never had the chance to buy that pack before the mall closed, you never had a chance to play with it. So I just thought it would be nice if people who didn't have a chance to get the quirky cookie machine had the chance to play with something similar.
